Answer:

For d=-2 rational expression will be undefined.

Step-by-step explanation:

Given function is \frac{6d-4}{d+2}

We need to find for what value of variable d this rational expression will be undefined.

The rational expression will be undefined if the denominator of the expression will become zero.

So, let us plug denominator equal to zero.

d+2=0\\\\Subtracting\ both\ side\ 2\\\\d+2-2=-2\\\\d=-2

Hence, this rational expression will be undefined if the value of variable d=-2.
